The utility model discloses an engine water pump belt pulley press fitting device which comprises a base, a supporting plate, floating devices and a distance measuring sensor, a vertical pump shaft can be supported in the middle of the base, the supporting plate can float up and down on the base through the floating devices arranged in a matrix mode, the supporting plate is used for positioning a pump shell, and the distance measuring sensor is fixed on the base. The distance measuring sensor is used for determining whether the supporting plate moves to a stop position; according to the utility model, a fixed reference surface in a traditional scheme is changed into a floating reference surface, and a movable supporting mechanism is changed into a fixed supporting mechanism; the floating reference surface is adopted, the actual position of the measurement reference is used as the relative reference of the servo system, and the press-fitting size of a product is directly used as a press-fitting increment displacement value by the press-fitting machine control system, so that the mounting size is ensured, and the problem of damage to a bearing is eliminated.

The invention discloses a submersible motor with self-cooling circulation and a submersible pump using the submersible motor, and relates to the technical field of submersible electric pumps, the submersible motor comprises a stator assembly, a rotor assembly and a front cover assembly, and is characterized in that a motor shell is mounted outside the stator assembly and the rotor assembly. According to the invention, the stator iron core and the stator winding are wrapped and protected by the front stator shielding case and the rear stator shielding case, on the basis of the original punching sheet diameter, the length of the iron core can be reduced, the output power can be improved, the original installation size can be ensured, and the increase of the diameter of the submersible motor and the difficulty of the design of a submersible pump flow channel caused by the increase of the punching sheet diameter can be avoided; damage of the bearing is reduced, the submersible motor can be conveniently applied to the submersible pump, the self-cooling effect of the motor and the submersible pump in use is guaranteed through an existing cooling mode, small-space water flow circulation at the two ends can drive local water flow to pass through a sliding bearing gap for lubrication, and meanwhile the sliding bearing is cooled.

This utility model relates to the technical field of fuel-powered vehicles and new energy vehicles, and discloses a liquid-cooled plate riveting bracket anti-rotation positioning structure, including a bracket and a manifold. The bracket has a first rivet hole, and the manifold has a second rivet hole. The bracket is connected to the manifold by a rivet. The rivet passes through the first rivet hole and the second rivet hole to connect the bracket and the manifold. The end face of the manifold near the bracket has a circular hole structure, and the end face of the bracket has a square slot structure above the circular hole structure. A barb structure is integrally provided on the square slot structure. The barb structure passes through the circular hole structure. The barb structure of the bracket in this utility model can be inserted into the circular hole structure on the manifold. Finally, the rivet is installed. At this time, the relative position between the bracket and the manifold is unique, ultimately meeting the customer's requirements.
